Question

a student placed a stack of rocks on a ramp. she added clumps of soil rooted with live grass. using a garden hose, she then applied a steady spray of water that soaked into the soil, making it heavier. what does the student’s experiment model? a. mass wasting b. wind erosion c. biological weathering d. chemical weathering

Explanation:

The student's experiment involves adding water to soil on a slope, which can cause the soil - rock mass to move downslope due to gravity. Mass wasting is the movement of rock and soil down a slope under the influence of gravity. The added water makes the soil heavier, increasing the likelihood of movement. Wind erosion involves wind - carried particles wearing away surfaces. Biological weathering is the breakdown of rocks by living organisms. Chemical weathering is the decomposition of rocks through chemical reactions. This experiment best models mass wasting.

Answer:

A. Mass wasting
